    Anyone growing this orchid? If so, can you provide me with some culture notes? I've exhausted the internet with not much luck. Thanks!

    no, but i have a young o. schweinfurthiana............. i keep it outside, in dappled sun/shade (am sun, afternoon dappled sun). it will eventually grow into more sunlight as it gets taller. i got a little seedling about 2 years ago. it was maybe 4 inches tall. now it is maybe 2 feet tall on the tallest 2 growths. so far it is my orchid that can handle the most california sunshine. very hardy. it is planted in a huge pot with my dragon fruit cactus, and a few other terrestrial orchids. the pot is filled with regular potting soil, with a 3 inch deep layer of orchid bark mix on top. i use old orchid mix from repotting as mulch in my larger planters. this orchid is basically tucked into the top mix, with roots going down into the soil. i used to keep it in a smaller pot with small orchid bark mix. it did just as well. but bright light is a must. it has nearly died twice, once from not enough light (my bad) and a severe mite attack took off all the leaves once. now i routinely spray with neem once a month, but after the sun has gone down to avoid burning the leaves. this looks like a small and delicate epidendrum reed-stem. i was told similar culture would suffice, and so far it has. the one you have would be my next one i go after, if i can bloom mine. not much info out there for sure. bright light, evenly moist. i'm hoping these are so easy to grow people don't think we need any more info?

    I have not grown this species but checking the internet It enjoys bright light, intermediate temperatures, good humidity and air movement. It grows well in plastic pots with moss or a seedling bark (Paph) mix. Evenly moist

    btw, these were once epidendrums, so maybe you can locate info under the older name?

    Some info summarized from Baker culture sheet in OrchidWiz

    LIGHT: 2500-3500 fc. no direct mid-day sun

    Strong air movement

    TEMPERATURES: average days 78-84F, nights 67-69F

    HUMIDITY: 70-85%

    Water heavily while actively growing, but drainage must be excellent

    FERTILIZER: 1/4-1/2 recommended strength, applied weekly when plants are actively growing

    No rest period, but water and fertilize less when not in active growth

    MEDIA: coarse, open, fast-draining medium that allows the roots to dry rapidly after watering. Undersized containers with room for only 1-2 year's growth


    And from my own experience with this genus... EXTREMELY susceptible to spider mites if humidity is low

    I plan to grow Oerstedella species again, but the next time I promise to pay attention to the exposure of the pot to direct sun; I managed to cook the roots! I lost several orchids to this (dark plastic pots and lights through windows or direct sunlight outdoors hitting pots that were not shielded.). I now place aluminum foil on the window side of pots that are on the south and west exposures, except for those plants that are double-potted with wet media between the pots to lower root temperatures. Then I'm using terracotta or concrete pots for the outer pot.
    I loved the heavy displays of small flowers on the Oerstedella spp., and also on the Barkeria.

    I grow everything in baskets so I hope not to have that issue, but thanks for bringing it to my attention! I've never contemplated cooking the roots!
